c# - If a method performs operations on a reference type is there any need to return it? -

-

If I have a method that operates especially on a reference type variable (such as a dataset) and modifies it , Then there is no need to return that variable to the method ??

For example, the following method goes through a data and trim all the values ​​within it and then returns the dataat to the caller: 

  private datatyll TrimAladataDataTable (Datatelle DT) {foreach (Detroit Row in dt.Rows) {foreach (Datacolumn DC in dt.Columns) {Line [DC] = Line [DC] .Ostring () Trim (); }} Return DT; }

Would it be better if this method is devoid of zero? This (?) Seems very nonsensical to return, but do you think it reads better if it returns the item after operating it (as it does at this time) ??

For me, when a method returns a reference type, then I hope it is a new one Be an object. I decide to withdraw it from zero.

One question: Is there any reason for this method not to be a member of the DataTable class? I think that DataTable.TrimAllData () will also work better

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for.

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
